I've read a lot of bad stuff about the MX Rev, I think for all round PC/Game/ use the MX1000 is the best you get.
I could not use a Gaming mouse overall and was interested in the MX Rev when it launched.
Hopefully Logitech will do a new high end Mouse/KB kit again that's not Bluetooth and its about time to revamp the MX Rev as its getting on.
I have just been sent an MX Revolution as areplacement for my MX1000 and have been told that when it arrives I ahve to cut the USB plug of the current cble and send it back to Germany!
